                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Afternoon rainclouds cleared off by sunset.  We missed some of our
 regular cooling-time, but opened well in time for the scheduled start
 of observing.  First half began with occasionally cloudy skies and
 surprisingly reasonable seeing.  A storm to the northeast was
 approaching all evening, dissipating as it got closer.  By the end of
 first half, the moisture and high winds reached us even though the
 rain didn't, and we had to close.
 When the wind and humidity had stayed down for a bit, I re-opened.
 The sky was mostly clear but the seeing was poor and variable --
 anywhere from 1.5 to worse than 3 arcseconds.  It was very hard to
 find a good focus under such conditions, but we got some useful
 data.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
